Figure 4. A and B: HF before (â—) and after (â– ) 8-weeks of HIIE plus strength exercise. a = lower than 30-min post exercise session; b = higher than 10-, 20- and 30-min post exercise session. C and D: LF before (â– ) and after (â—) 8-weeks of HIIE plus strength exercise. a = lower than 10 and 20-min post exercise session. E: Behavior of LF/HF ratio before (â– ) and after (â—) 8-weeks of HIIE plus strength exercise.
